Technical field
The present invention relates to a kind of crank driving mechanism of microtome arbor.This crank driving mechanism comprises in other words axle of the first and second arbors.The first arbor can be rotated by crank.The first arbor has the first driving component.The second arbor has the second driving component.The rotation of the first arbor can be delivered on the second driving component of the second arbor by the first driving component.The second arbor can place rotation thus.Common the first driving component forever is connected un-rotatably with the first arbor.The second driving component forever is connected un-rotatably with the second arbor in the same way.
Background technique
The crank driving mechanism that begins described microtome arbor uses especially in the applicant's sliding type microtome, namely in " Leica SM2000R " type microtome.This sliding type microtome in company's sample in March, 2003 with the pamphlet explanation.For the sliding type microtome, the cutter of cutting object moves back and forth at the slide plate of arranging movingly, is arranged in object in the object fixing frame with cutting.The object fixing frame by corresponding mechanism be micro-adjusting mechanism vertically towards tool motion, this is also referred to as feeding.Object can be by establishing graduated knob accurate adjustment until 0.5 μ m towards the increment of the direction feeding of cutter.Be provided with crank as other operating element at above-mentioned sliding type microtome, utilize this crank can realize going or leaving towards cutter basically in the vertical direction the thick transmission of object motion of cutter.After sample is changed, can make thus the object fixing frame together with object fast towards tool feeding, can directly follow with hope cutting thickness that can be given in advance like this and carry out cutting process.Be arranged on the operating handle with knob (trip(ping) lever) that leads in the slotted hole as other operating element, utilize it can start the object fixing frame towards the manual feed campaign of cutter.Knob in other words operating handle usually only uses during feeding in cutting work, and wherein feeding is provided with the increment that the knob of scale adjusted at that time with utilization and carries out.This sliding type microtome also comprises the working state of utilizing automatic feed, and wherein the associative operation planning is on the microtome slide plate.The manipulation of trip(ping) lever is used and is replaced in this automatic feed usually when the cutting sample.
In view of the crank driving mechanism that is used for thick transmission at that time only with, when clockwise rotating, cause feeding.Correspondingly when crank driving mechanism rotates counterclockwise object in other words the object fixing frame leave in other words from cutter and descend.What now probable value must be pursued is, utilizes counterclockwise rotation also can cause the feeding of object, is left-handed people and another operator is the right-hander because different operators operates same sliding type microtome and operator for example.Such requirement can only be satisfied so far thus, namely prepare two kinds of different sliding type microtomes, namely utilize a kind of sliding type microtome to carry out feeding by the clockwise rotation of crank, and cause feeding for the counterclockwise rotation of another kind of sliding type microtome crank is corresponding.Namely the sense of rotation of crank driving mechanism is in advance fixing setting of configuration aspects.
Summary of the invention
Therefore task of the present invention is to illustrate and improves the particularly crank driving mechanism of sliding type microtome arbor of microtome, utilizes it can realize respectively feeding or the decline of object with same crank driving mechanism two opposite sense of rotation in same microtome in thick transmission.
The crank driving mechanism according to the present invention that begins described type solves above-mentioned task by the feature of claim 1.Then such crank driving mechanism is characterised in that, is provided with the 3rd driving component.The 3rd driving component also can forever be connected with the second arbor un-rotatably.The first driving component can mesh with the second driving component or the 3rd driving component selectively, and the sense of rotation of the first arbor is reversible in the situation of the sense of rotation that keeps the second arbor so thus.In other words by the first driving component selectively with the engagement of the second driving component or the 3rd driving component, the sense of rotation of the first arbor is reversible, according to the driving component engagement situation at that time of two participations, object can utilize the clockwise rotation of crank or utilize the counterclockwise rotation feeding of crank like this.
At first known according to the present invention, do not need to prepare the microtome of the different design proposal of two kinds of structures, namely for example can provide microtome to his best operated for left-handed people.Provide additional mechanism to the mechanism of the so far thick transmission of sale more precisely, it is reversible utilizing the sense of rotation of this additional mechanism providing additional operation first arbor in the situation of the sense of rotation that keeps the second arbor.Should additional mechanism mainly comprise the 3rd driving component and can make the first driving component selectively with the mechanism of the second driving component or the engagement of the 3rd driving component.
The microtome of same tool additional function scope likely can be provided in particularly advantageous mode by this can be relatively under individual cases simple and that cost is made economically measure, realize that namely the thick transmission of object feeding can be adjusted selectively two sense of rotation.No longer need thus, two kinds of almost identical structural types are provided, the microtome that only has respectively a thick transmission sense of rotation different and that can not change.
Driving component designs like this in a kind of particularly preferred mode of execution, and the first driving component can form fit mesh with the second driving component or the 3rd driving component with being connected.The transmission that connects by the form fit that rotatablely moves can realize not having slip and other transmission loss ground to be delivered on the second arbor from the first arbor by the operator in the rotation that crank is implemented usually.Each gear pair is suitable for the driving component as the form fit connection in principle, and wherein the first driving component has a kind of gear-type, and it is designed to and the second in other words gear-type complementation of the 3rd driving component basically.Specifically first, the second and/or the 3rd driving component can have respectively gear, bevel gear, cylindrical gears, helical teeth-cylindrical gears, worm gear is worm screw or worm shaft in other words, utilizes or rather this condition, and the first driving component can complementally be meshed and the first driving component and the engagement of the second or the 3rd driving component basically with the second and the 3rd driving component.
Driving component can design so in another embodiment, and namely the first driving component can power transmission be connected the ground combination with the second or the 3rd driving component.When the first arbor is delivered on the second arbor slippage loss may occur when rotatablely moving in this case.But this may be favourable, when object under when facing the tool orientation feeding, cutter directly is positioned at the top of object and continues when the operator neglects and moves upward, object is pressed onto on the cutter and may damages thus.The characteristic of the transmission that can connect according to the power transmission of selecting in this case stops the continuation feeding of object, if namely object in other words the object fixing frame since resistance can not continue again to move upward.The the first, the second and/or the 3rd driving component can have wheel specifically, and it has the surface of the suitable friction factor of the high characteristic of just having described in other words.
Can consider in principle now, the first driving component and the second driving component or the 3rd driving component are selectively realized in conjunction with being similar to Transmission gear.In this case namely for example the second and the 3rd driving component can be designed to the form of floating roller, in other words namely be not forever to be connected with the second arbor un-rotatably.Utilization connect un-rotatably on the second arbor, can be arranged in the gear shift combined cover between the second and the 3rd driving component, the second or the 3rd driving component is connected with the second arbor un-rotatably.The first driving component is combined with the second and the 3rd driving component enduringly in this case, and the rotation of the first arbor by the first driving component continuously and be directly delivered to the second and the 3rd driving component.According to the position of gear shift combined cover, the rotation of the first arbor is delivered on the second arbor by the second driving component or by the 3rd driving component.If the gear shift combined cover has a neutral position, neither between the second driving component and the second arbor, between the 3rd driving component and the second arbor, there is not non-rotatable connection in this position yet, then two arbor machineries are thrown off.
As relative the second arbor of the first arbor being moved like this by translational motion with the replacement scheme of the similar gearshift mechanism of Transmission gear, the first driving component can be combined with the second or the 3rd driving component.In other words namely all arbors together stand translational motion with the crank that may fix thereon.Be provided with the guiding element on the housing that is arranged in accordingly microtome for this reason.The translational motion of arbor is repeatably and satisfies purpose thus.Can basically relate to straight line motion for this translational motion, all be admissible although rely on arbitrarily the translational motion of each existing Boundary Conditions in Structures.Also can consider in this connection, arbor is turning to be arranged in other words swingably like this, and the first driving component can be combined with the second or the 3rd driving component.This axis of oscillation in other words of overturning is arranged in other words around the longitudinally axis orientation transverse to the arbor that swings in other words of upset in this case.
In a kind of particularly preferred mode of execution, relative the second arbor of the first arbor can move like this by rotation or oscillating motion, and the first driving component can be combined with the second or the 3rd driving component.Whole arbor is rotated in other words and swings in this case, or rather around be arranged essentially parallel to the rotatable arbor of arranging swingably in other words vertically and the rotation that is staggeredly arranged of side direction in other words axis of oscillation arrange.
In configuration aspects, if the first arbor is rotatably supported in decentralized casing in the eccentric position, rotatablely moving of the first arbor can be realized by the rotation of decentralized casing so.Such organization plan is cost economy, and can utilize relatively simple mechanism to make economically.The size of the arranged off-centre of arbor in decentralized casing generally depends on the space of the second and the 3rd driving component and arranges, so i.e. rotation by decentralized casing can be combined the first driving component selectively with the second or the 3rd driving component.
Decentralized casing can connect the switch panel that can be handled by the operator un-rotatably for manual control.Can stipulate in addition, decentralized casing directly is rotatably supported in the bearing of microsection engine housing or in the axle sleeve, wherein this axle sleeve position is fixed on the housing of microtome regularly.The arbor, decentralized casing and the axle sleeve that just have in this point driving component can form modular parts, and this manufacturing that can significantly simplify microtome is produced in other words.
Now switch panel and decentralized casing can design like this, namely turn at switch panel≤270 degree, and during the angle value of preferred 180 degree, crank driving mechanism can place the second working state from the first working state.The first driving component is combined with the second driving component under the first working state, and the first driving component is combined with the 3rd driving component under the second working state.In other words the conversion between two kinds of working staties can turn over less angle value and need not turn over a plurality of complete number of turns by switch panel and realize, be thus gear shift can be fast with manually be implemented by the operator simply.
Can be provided with end stop in addition, the in other words rotation of decentralized casing of their limit switch dishes.Can be adjusted in the position of an end stop the first working state and be adjusted into the second working state in the position of the second end stop.A Fastener and at least two and two kinds of chucking positions that working state is corresponding can be set in addition, namely guarantee switch panel in other words decentralized casing remain in the position of the corresponding working state of being adjusted by the operator respectively.
Be provided with a kind of working state in a kind of particularly preferred mode of execution, the first driving component neither is combined with the second driving component under this working state, also is not combined with the 3rd driving component.For this working state can be distributed a chucking position equally.The first arbor and the second arbor are mechanically thrown off under this working state, with when the cutting of back and the very little feeding in the 1 μ m order of magnitude that is attached thereto, can frictional loss or the resistance of the first arbor cause the interference of blocking in other words feeding in other words owing to crank.If the operator blocking of feeding can not occur owing to neglecting fixed crank and fixing thus the first arbor yet in this connection.
Present the first arbor can be connected with crank un-rotatably.If correspondingly for example crank rotates half-turn, then arbor rotates half-turn equally.What scheme was passable as an alternative is, the rotatablely moving of crank can utilize can be given in advance reduction speed ratio or the transmission intergrade of velocity ratio be delivered to the first arbor in other words on the first driving component.This velocity ratio can be selected so in this case, if namely for example crank is by operator's manual rotation one whole circle, then arbor rotates two whole circles.Remaining structural characteristics of microtome and mechanical actuation device coefficient with it are generally depended in the selection of velocity ratio.
